S&P 500 Q2 earnings grew 31% year-over-year, significantly surpassing Wall Street's 23% expectation, marking the strongest growth rate in a non-recessionary recovery period since 1992.

U.S. companies significantly outperformed expectations this earnings season, with S&P 500 earnings growing by 31% year-over-year in the second quarter. This not only substantially exceeded Wall Street's prior expectation of 23% but also marked the strongest growth rate since Bloomberg Intelligence began tracking data in 1992, excluding periods of recovery after major recessions. The primary drivers behind this performance were the accelerated penetration of artificial intelligence (AI), which compressed costs and boosted profit margins, and the U.S. economy's better-than-expected resilience despite multiple headwinds. The S&P 500's price-to-earnings ratio has now fallen from approximately 26x at the beginning of the year to below 22x, indicating that valuations are being absorbed by earnings growth. Wall Street strategists are optimistic about the earnings outlook, having raised their year-end target for the S&P 500 to 7894 points and their full-year earnings growth forecast to 27%. Furthermore, MSCI Europe index earnings grew by 18% year-over-year in the second quarter, and the MSCI Asia Pacific index saw its earnings forecast revised up by nearly 10%, demonstrating a synchronized strengthening of global earnings.
